Cancer cell growth
BPA is not the only chemical in plastic that can enter our bodies through food, water, and air in the form of microplastics. Phthalates, a chemical used in plastic production to give the material flexibility, have been linked to cancer cell growth, particularly on breast cancer studies.
More studies are needed, but there’s a high probability that microplastics and the chemicals released from them once they enter our bodies also encourage the development of gastrointestinal cancers.
